Question

PlZ answer this both questions ​

Answer 1

Step-by-step explanation:

7) angle y = 65° (corresponding angles)

angle x = 50° ( corresponding angles)

8)angle acb = 180° - (80°+35°)

= 65°

angle abc = 180°-(80°+65°)

= 35°

Answer 2

Answer:

7.  x = 130 degrees

    y = 115 degrees

8. 35 degrees

Solution:

7.

angle x

• angel 3 is equal to angle 1 because they are corresponding angles. So, it means that angle x is equal to the angle on the right side of angle 3.
• We subtract 50 from 180 (180 is an angle of a straight line)
• 180 - 50 = 130
• x is 130 degrees so is the angle on the right side of angle 3 because they are corresponding angles.

angle y

• same as angle x.
• 180 - 65 = 115
• y is 115 degrees so is the angle on the left side of angle 4.

8.

• we all know that the total angle of the interior of the triangle is 180 degrees.

• we need to subtract 80 and 35 from 180 ( 180 is an angle of a straight line)
• 180 - ( 80 + 35) = 65
• so angle BCA is 65 degrees
• 180 - (65 + 80) {we do this to find out the angle of ABC
• 35 degrees
